  • the cutting part 55 is provided with a plurality of through holes 61 passing from the external surface 60 to the internal surface 70, wherein each hole 61 has a segment AA and a complementary segment BB of the edge 62 that define it peripherally.
  • the segment AA and the complementary segment BB may have different inclinations.
  • the segment AA may have an inclination of an angle ⁇ 1 with respect to a reference plane P tangent to the external surface 60 passing through the centre C of the hole 61.
  • the segment BB may have an inclination of an angle ⁇ 2 with respect to the reference plane P.
  • the angle ⁇ 2 is preferably smaller than the angle ⁇ 1.
  • the segment BB is able, by means of a punching operation, to assume a protruding shape suitable for the production of the cutting part 55 ( Figs. 3b, 4b , 7a-d ).
